4) Continue following the highest reading until the signal starts weakening. This is the point of the
fault as the signal flows to ground instead of continuing strongly down the shorted conductor.
Reduce the sensitivity range and use the nose of the receiver to pinpoint the source of the fault.
Higher Voltages (3 Phase WYE or DELTA Systems)
When using the alligator clips to attach the transmitter to live voltage that is greater than 120 VAC use
the following method. Install the alligator clips to the ends of the 3 foot leads. Do not plug them into the
transmitter. Using appropriate PPE procedures, attach the alligator clips to any two of the 3 live phases.
Next, plug the safety leads into the terminals on the transmitter, polarity is not important. Now turn the
transmitter on and note if the line energized light illuminates. Proceed with your tracing or fuse or breaker
identification. To disconnect, turn the transmitter off, and remove the terminals from the transmitter. Next,
using appropriate PPE procedures disconnect the alligator clips from the energized conductors. When
tracing 3 phase systems use the same procedure but attach to any two of the three phases.
